We throw beans inside the house or around the house with the windows and doors open and shout

「鬼は外！福は内！」

= Oni wa soto! Fuku wa uchi!

= “Demons out! Good luck in!”

This will get rid of bad luck and invite in good luck. One person, usually a father, wears the 鬼 ( = oni) demon mask and the rest throw beans at that person. It’s customary to pick up the beans off the floor and eat the number equal to your age in the hope that this will get you good health and good luck.

Haha, this is actually a really great way of learning. It is not designed towards beginners however it does break down the sentences and information very well for studdy. After finding this page after your youtube advertisment, im sure i will keep poping back to try and educate myself alittle bit more. ^^ – Jay.
